    Abstract: Process for regeneration of a catalytic moving bed in which the catalyst successively passes through at least one combustion zone A, at least one halogenation zone B, and at least one calcination zone C, whereby this process operates in a partial-regeneration-mode, the partially coked catalyst that is obtained from the last combustion zone passes into the halogenation zone in which the amount of halogen and the amount of oxygen are essentially zero--the valves of tubes (19) and (20) are then virtually closed--and the catalyst then passes through the calcination zone in which the amount of oxygen is essentially zero--the valve of tube (11) is then virtually closed.

    Abstract: A process for transferring catalyst particles between multiple reactions zones simplifies the system for use of a single valve operation by passing a purge gas into a lower section of a reaction zone that discharges catalyst from the reaction zone into a lift vessel and uses the intermittent introduction of a lift gas stream to entrain catalyst particles in a dilute phase upward lift step to a succeeding reaction zone while simultaneously retarding the flow of catalyst particles down the discharge conduit and interrupting the flow of purge gas down the discharge conduit. In this manner a flow of purge gas can constantly enter the reaction zone supplying catalyst particles to the lift system thereby preventing any flow of reactants from the reactor into the lift system while only the addition of lift gas into the lift system needs to be cycled on and off to intermittently transfer the catalyst particles upwardly in dilute phase to the top of the next reaction zone. Therefore, the whole system can transfer catalyst particles indefinitely with the operation of only one valve that is not in catalyst service. As a result additional equipment such as disengagers, control valves and conduits for venting gas and interrupting catalyst flow is eliminated.

    Abstract: A process for the simultaneous replacement of a first catalyst by a second catalyst which first catalyst is circulating as a moving bed of solid particles in a hydrocarbon treating unit, which unit comprises at least one processing reactor. The first catalyst is withdrawn downstream of the reactor, or of each reactor, in the direction of catalyst circulation. The second catalyst is simultaneously injected upstream of the reactor or of each reactor. The bulk density of the material withdrawn downstream of the reactor, or of each reactor, is measured continuously. The withdrawal of the first catalyst and the injection of the second catalyst into the reactor concerned are interrupted when the bulk density so measured is equal to that of the second catalyst.
